Maybe one of you APL experts out there can answer a question for
me (an occasional APL user):  what ever happened to the "I-beam"
operator I seem to remember reading about a while ago?  I-beam
was formed by overstriking the "represent" (looks like T) and
"base" (upside-down T) symbols and (if I remember) could be used
to return certain system information.  It was used something like

                         I27

where 27 (or whatever) was a number indicating the system info you
wanted.  None of the PC-based APL systems I've used seems to have
this.  What gives?
  Thanks for your help!
